Susie Wolff will get more time in the Williams cockpit this season with the team confirming her for a couple of Friday drives.
The Brit was appointed test driver earlier this year and she has already spent some time behind the wheel of the FW37 as she took part in testing in Barcelona.
The Grove squad have now revealed that she will also be in action on one of the test days in Austria in June as well as Free Practice One sessions at the Spanish and British Grands Prix.
"Our focus this year is to build on the success of 2014 – I've been training hard all winter and I am physically in the best shape I’ve ever been, so I am ready for the season ahead," Wolff said.
"As Official Test Driver I will have additional time in the FW37 and by correlating this with my work in the simulator, the team can ensure we are getting the best from the car and check how updates are performing. All of us drivers on the Williams roster have been working closely together on this and we are ready to give everything we can to the 2015 season."
Williams deputy team principal Claire Williams feels it is only right that Wolff is handed more opportunities.
"Last season Susie impressed with her performances during FP1 at Silverstone and Hockenheim and we were keen to give her another chance to test in 2015," she said.
"She knew the FW36 well and with the FW37 being a gradual evolution, we were keen to utilise this knowledge and get her in the car to help assess and validate the approaches we have taken."
